Review on KOIOS Purifier Upgraded Ultraviolet Eliminator by Monica Satchell

I bought this air purifier to reduce pollutants in my house during wildfire season. After going through an unhealthy air quality cycle last week, I found that the air quality sensors on this unit are not set to AQI or PM2.5, the most common air quality measures. I measured within AQI 150 (unhealthy) where this air purifier reported blue or "better" air quality on its three-tier (blue/green/red) rating system. Thus, it is clear that you cannot rely on the automatic settings of this device to control the health-related air quality of your home. The device's sensors will detect if you've got perfume, air freshener, or something cooking on the stove, but it's frustrating that you can't rely on this air purifier to monitor air quality and protect your home from unhealthy air, especially during They sleep. The benefits of this air purifier are pretty simple: it costs about half the price of similarly rated devices that are actually tuned to the air quality of interest, it's quiet enough, and its filter improves actual quality without the knowledge of its own air quality sensors.air. Air quality during operation. I used one of these units at full fan speed to maintain an AQI of 50 in a >1000 sq ft room while the AQI was 150 outdoors. So it's something. The remote control is less of a feature and more of a responsibility because as far as I can tell there are some important functions of the device that can only be controlled via the remote control. Namely: a sleep function (basically a very low fan setting) and a lights-off function (two of which could probably be one button on the remote instead of two, but that's another discussion). The real problem is that the air purifier does not have such buttons. So if you lose the remote, you lose those features. But that problem isn't solved, because if you want to be sure you don't wake up in a room with an AQI of 150+, you'll have to manually keep the device above the sleep setting. So, to recap, if you're looking for an air purifier that will keep your home's air quality healthy, this device is like a neat version of a mirv16 filter glued to a box fan. If you buy something that helps fight odors, it may be better suited to your needs.
